Full screen zoom fails in Chromium

[Veiokej]

I'm not sure if this is a Unity issue or an editor issue, but the same problem on 2 different editors would suggest the former. Open either of these editors. Double-click on the title bar to zoom. (Once you do this, you may never again be able to shrink the window again, beyond a small fractional amount, because you will never again be able to reach the bottom border with the "up-and-down resize arrow"; you would need to reinstall the OS!)

Zoom works fine. Now close the editor.

Launch it again. This time, it tries to come up zoomed, which makes sense because that was its most recent state. But the last line of text at the bottom of the screen shows through. (In other words, it would be a full-screen zoom, but the last line is still the desktop background.) So you need to double-click on the title bar twice, once to shrink and another time to zoom again. The second time, it actually zooms correctly. When you open another file or repeat the experiment, you need to quadruple-click all over again.

In addition to being very awkward, this is actually quite confusing, because if you have zoomed and unzoomed editor windows open, the last line of text from document A shows up at the bottom of document B.

This problem did not happen on i386 12.04 several months ago. Sorry, I no longer have the specific details. Anyway, it happens now on AMD64 12.04. Reinstalling the OS fixed it for a few sessions. Then it happened again. Perhaps zooming triggers it.

I have some sense that this bug relates to the fact that Unity has its own title bar at the top, so somehow the editor is getting the wrong idea about how big "full-screen" really is.

The reinstall-the-OS-to-resize issue is perhaps another bug, but I'm not going to open another report at the moment because I suspect that it's due to the same root cause.

Any news on this issue? Can it be reproduced in Ubuntu 14.04 or newer?

[Veiokej (veiokej)]

Still happens in 14.04, although in my current instance, it only happens with Chromium and not the two editors mentioned above (screen resolution dependent?). Once you zoom Chromium, you can never use the lower-right-corner-arrow thingy to resize it (while unzoomed) again. AFAIK, I need to reinstall the OS in order to restore that ability. Might be related to the annoying drag-to-top autozoom feature which turns the window yellow and spontaneously zooms it. Not sure.

I will update the bug status to reflect the new bug description. Thanks.
